Volvo: Volvo C70 - 2001 - stalls after start up, volvo c70, immobilizer system

Question
Hi Jimmy

2001 C70 2.0 Turbo AUTOMATIC

When I start up, it usually will start OK for 2-3 seconds, then shuts down. If I try again immediately afterwards, it will do the same again. On the 3rd go, it wont start at all. If I leave it 10 mins and try again, I may be lucky and it will start. Battery is fine, it doesnt vary if I havent used the car in a few days either. Its random - doesnt happen every time, but most times. I need to get the foot down fast on acceletor to keep momentum and engine turning over just after start up to keep it going.
Its an automatic - according to manual I shouldnt need to so that. Many Thanks.

Hello! The may be a problem with the immobilizer system. The most common cause is antenna ring. The key has a transponder in it that sends the signal to start the car. The problem can also happen if there are 2 or more keys on your ring that have a transponder in them. A diagnostic check by a Volvo technician will be the best way to find out.
